Description

Technical Field

[0001] The utility model relates to the technical field of scaffold installation, in particular to a novel scaffold for construction. Background Technique

[0002] The scaffold for construction is an indispensable temporary facility in building construction. It provides a safe working platform for construction workers and also undertakes the task of supporting materials and equipment. There are various types of scaffolds, including fastener-type, portal-type, bowl-coupling type, disk-coupling type, aluminum alloy, etc. Each type has its own characteristics and applicable occasions. The structure of the scaffold generally includes a main body mechanism, a connecting mechanism, a fastening mechanism and other auxiliary mechanisms.

[0003] When installing the scaffold, it is necessary to ensure safety and the stable installation of the scaffold. In the prior art, most of the novel scaffolds for construction stabilize the upper frame body through a bottom flat support structure, with a low degree of stability. Scaffold tipping accidents often occur, which cannot effectively guarantee the safety of construction workers and reduces the practicability of the device. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a novel scaffold for construction, aiming to improve the problem that most of the novel scaffolds for construction in the prior art stabilize the upper frame body through a bottom flat support structure, resulting in a low degree of stability and reducing the practicability of the device.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A novel scaffold for construction includes four vertical rods. Two lower supports are fixedly connected to the opposite sides of the four vertical rods. Two upper supports are fixedly connected to the opposite sides of the four vertical rods. A working board is fixedly connected between the four vertical rods. Protection frames are fixedly connected to the tops of the four vertical rods. Two U-shaped frames are fixedly connected to the outside of the vertical rods. Rotating shafts are rotatably connected to the interiors of the two U-shaped frames. Torsion springs are arranged in the interiors of the two U-shaped frames. An upper stabilizing rod is rotatably connected to the interior of one of the U-shaped frames. A lower stabilizing rod is rotatably connected to the interior of the other U-shaped frame. A stabilizing shell is fixedly connected to one end of the upper stabilizing rod and the lower stabilizing rod away from the vertical rod. An inner shaft is rotatably connected to the interior of the stabilizing shell. A pedal is fixedly connected to the outside of the inner shaft. A plurality of connecting disks are fixedly connected to the outside of the inner shaft. A connecting rod is rotatably connected to the top of the connecting disk. A plug rod is rotatably connected to the end of the connecting rod away from the inner shaft. A plurality of insertion holes are formed in the outside of the stabilizing shell. Moving mechanisms are arranged at the bottoms of the four vertical rods, and the moving mechanisms are provided to facilitate the adjustment of the overall structure position.

[0006] As a further description of the above technical solution:

[0007] The moving mechanism includes four universal wheels. The tops of the four universal wheels are rotatably connected to the bottoms of the four vertical rods. One side of each universal wheel is fixedly connected with an installation shell. A spring is fixedly connected inside the installation shell. One side of the spring close to the universal wheel is fixedly connected with a limit block. A pin rod is fixedly connected inside the limit block. Card holes are formed in the outer parts of the four vertical rods, and the pin rod is engaged with the card holes.

[0008] As a further description of the above technical solution:

[0009] One end of one of the torsion springs is fixedly connected inside the U-shaped frame, and the other end of one of the torsion springs is fixedly connected to the outside of the upper stabilizing rod.

[0010] As a further description of the above technical solution:

[0011] One end of one torsion spring is fixedly connected inside the U-shaped frame, and the other end of the other torsion spring is fixedly connected to the outside of the lower stabilizing rod.

[0012] As a further description of the above technical solution:

[0013] The insertion rod penetrates through the inside of the insertion hole, and a ground plug is fixedly connected to the bottom of the stabilizing shell.

[0014] As a further description of the above technical solution:

[0015] A bolt is threadedly connected to the top of the inner shaft, and an anti-slip sleeve is sleeved on the outside of the bolt.

[0016] As a further description of the above technical solution:

[0017] One end of the pin rod away from the universal wheel is fixedly connected with a push-pull ring, and a protective sleeve is arranged on the outside of the push-pull ring.

[0018] As a further description of the above technical solution:

[0019] The limit block is slidably connected inside the installation shell, and the pin rod penetrates through both ends of the installation shell.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the present utility model, when the scaffolding is pushed to the working position, the universal wheels are retracted. By stepping on or hammering four pedal plates with heavy objects, the four stabilizing shells are integrally pressed into the ground. The inner shaft is rotated, and through the connecting plate, the connecting rod pushes the insertion rod to extend out of the insertion hole and insert into the soil to enhance the stabilizing effect. The bolts on the inner shaft are tightened to prevent rotation. After all four stabilizing shells are fixed according to the above steps, workers can climb onto the scaffolding for construction operations. This realizes the effect of further strengthening the upper frame body through the stabilizing mechanism, ensuring the safety of construction workers and improving the practicality of the device.

[0022] 2. In the present utility model, when the universal wheels need to be retracted for scaffolding installation, by pulling the push-pull ring outward, the pin rod pushes the limiting block to compress the spring, thus releasing the locking state. The universal wheel is flipped upward until the pin rod aligns with the locking hole. Then, the push-pull ring is released, and under the action of the spring rebound, the pin rod pops out of the installation shell and engages with the locking hole to complete the retraction of the universal wheel. Conversely, the universal wheel can be lowered to push the scaffolding for movement. This realizes the effect that the moving mechanism can be folded and stored. During the scaffolding installation operation, the moving device will not affect the stable installation of the scaffolding, improving the practicality of the device. Description of the Drawings
